Abstract

ISO 10816-2:2009 establishes provisions for evaluating the severity of in-situ, broad-band vibration measured radial (i.e. transverse)to the shaft axis on all main bearing housings or pedestals and in the axial direction on thrust bearings. These are in terms of:

- vibration under normal steady-state operating conditions;

- vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes;

- changes in vibration which can occur during normal steady-state operation.
